"When time travel allows a past wrong to be righted for The Flash and his family, the ripples of the event prove disastrous as a fractured, alternate reality now exists where a Justice League never formed, and even Superman is nowhere to be found. Teaming with a grittier, more violent Dark Knight and Cyborg, Flash races to restore the continuity of his original timeline while this new world is ravaged by a fierce war between Wonder Woman's Amazons and Aquaman’s Atlanteans. With breath taking action and an all-star voice cast, it's a bold, emotional vision that will forever change the landscape of the DC Universe."

Newsarama reports that Kevin Conroy will return to voice Batman for this movie and Ron Perlman will be back as Deathstroke. Dana Delany will return as the voice of Lois Lane and Vanessa Marshall will do the voice of Wonder Woman. She also voiced the character in the Justice League: Crisis on Two Earths.
